"A survey of over 4000 low wage
workers in Chicago, Los Angeles and New York conducted by
university and non-profit researchers found: 26 percent of
the workers were paid less than the minimum wage in the
previous week, a majority were underpaid by more than $1 an
hour; a significant number worked overtime the previous week
and were not paid the legally required overtime; many were
required to come early or stay late and work "off the clock"
and were not paid for it; almost a third of the tipped
workers were not paid the minimum wage and more than 1 in 10
tipped workers had some of their money stolen by their
employer or supervisor."
